BACKGROUND

1. Field of the Disclosure

This application generally relates to a jacket for a handheld device. More particularly, this application relates to a jacket including an optical scanner positioned to allow a user to view a display on the handheld device while performing a task, for example, while scanning an item.

2. Description of the Related Technology

Some computing tasks or environments require a high degree of mobility, ease of operation, and low cost implementation due to a large number of users. One example of such a task is the administration and documentation of care provided to patients in a healthcare or hospital environment. Computer resources in these environments are limited due to inadequate availability of access points such as input/output (I/O) stations or terminals. Although stationary terminals may have a large screen, familiar full-featured keyboard, and mouse input devices, such terminals can be inconvenient to use in certain environments due to lack of portability, and/or availability due to cost and space constraints. Notebook computers with wireless communication capabilities can increase the convenience of computer terminals while maintaining relatively fast and available computing power. However, they are still somewhat large in size, bulky to transport, have limited battery life, require two hands to operate, are expensive, and/or can be damaged by exposure to liquids and/or solid particles (for example, dust or other debris).

A plurality of small sized wireless computing devices have been developed, such as wireless personal digital assistants (PDA's), for use by caregivers in administration and documentation of medical care. For example, U.S. Pat. No. 4,916,441 to Gombrich describes a handheld terminal that includes a wireless transmitter and a bar code scanner for entering medical data into a computer system. Unfortunately, a healthcare professional needs to manually type much of the information onto a small keyboard on the device. This is inconvenient and time-consuming in a healthcare environment. Further, this device is susceptible to damage caused by exposure to liquids and/or solid particles present in healthcare environments.

DETAILED DESCRIPTION OF CERTAIN INVENTIVE EMBODIMENTS

In the following detailed description, only certain exemplary embodiments of the present disclosure have been shown and described, simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. In addition, when an element is referred to as being “on” another element, it can be directly on the another element or be indirectly on the another element with one or more intervening elements interposed therebetween. Also, when an element is referred to as being “connected to” another element, it can be directly connected to the another element or be indirectly connected to the another element with one or more intervening elements interposed therebetween. Hereinafter, like reference numerals refer to like elements.

As noted above, the teachings herein can be applied in a multitude of different ways. For example, although the illustrated embodiments are configured for use with a non-cellular handheld device, for example, an iPod Touch®, embodiments can be configured for use with a variety of other handheld electronic devices, including, but not limited to, cellular phones, smartphones (for example, an iPhone®), VoIP handsets, wireless devices, bluetooth devices, personal data assistants (PDAs), handheld or portable computers, netbooks, notebooks, smartbooks, tablets, and other portable electronic devices. Thus, the teachings are not intended to be limited to the implementations depicted solely in the figures, but instead have wide applicability as will be readily apparent to a person having ordinary skill in the art.

In embodiments of the disclosure, a jacket or housing structure is provided for at least partially housing or encasing a handheld electronic device. In this way, the jacket and the handheld electronic device can together form a handheld computing device and/or handheld terminal. The jacket may include a connector assembly configured to connect to and communicate with the handheld electronic device. The jacket also can optionally include a transparent screen configured to align with a display on the handheld electronic device, at least when the device is connected to and housed within the jacket. In some embodiments, the jacket does not include a transparent screen and can include a sealing structure configured to circumscribe and engage at least a portion of a screen, input surface, and/or display surface of a housed handheld electronic device. In this way, the jacket and handheld device can engage one another to form a seal or barrier configured to protect components of the jacket and/or handheld device disposed below the screen of the handheld device and within the jacket. For example, a seal formed between the jacket and the screen of the handheld device can protect electronic components of the handheld device and jacket from solid particles and/or liquids that the resultant terminal or computing device may be exposed to. Further, the engagement between the jacket and handheld device can provide an absorbing structure configured to absorb impactful forces that may be imposed on the jacket and/or handheld device to prevent these impactful forces from harming or adversely affecting the functionality of the resultant terminal. In this way, the absorbing structure can allow the jacket and handheld device to be used regularly in a working environment, for example, a hospital.

In some embodiments, the jacket further includes an optical scanner and a scanning engine that communicates with the handheld device and/or an application on the handheld device at least when the device is connected to the jacket. The scanner, or code reader, can be used to read codes corresponding to, for example, patient identification, item identification, documentation characters and phrases, commands, and instructions. The codes are preferably machine readable codes, including one and two dimensional optically readable codes such as bar codes, but can include radio frequency identification (RF ID) devices or tags. The codes can be applied to objects, cards, or placards throughout a healthcare environment. By such a configuration, embodiments disclosed herein can allow for the use of a handheld electronic device, such as an iPod touch®, as an optical scanner (for example, a barcode scanner), adding to the capability of the handheld device. Embodiments can thus be used in various applications, including identification of medicines and patients, in healthcare workflow applications and other process control applications.

In some embodiments disclosed herein, the jacket can include a battery, for example, a lithium polymer battery, configured to provide power to the optical scanner, scanning engine, and/or handheld device. In some embodiments, the battery can supplement a battery provided with the handheld device. In this way, the battery can be configured to allow the handheld device and electronic components of the jacket to be used for an extended work shift, for example, for 12 or more continuous hours, without requiring a charge or a replacement battery.

In some embodiments, the jacket can be configured to be liquid-resistant, cleaning-agent resistant, and/or drop-resistant, so as to be usable in harsh environments such as, for example, a healthcare setting. For example, the jacket can include one or more resilient materials, for example, a resilient polycarbonate material. Such materials can be configured to absorb impactful forces present on the jacket without transferring such forces to internal electronic components. Further, such materials can withstand regular exposure to healthcare grade cleaning-agents without degrading. In this way, the jacket can be easily sanitized or cleaned. Additionally, as discussed below, the structures of the jacket and the handheld device can engage one another to create a seal to prevent the ingress of solid particles and/or liquids into an inner area of the jacket. In some embodiments, the jacket can include a microphone and speaker that communicate (for example, through the connector) with the handheld device. These structures can allow for the use of the handheld device (including a non-cellular device such as an iPod touch®) as a verbal and aural communication device, such as, for example, a voice over internet protocol (VoIP) handset.

FIG. 1A shows a perspective view of a jacket 100 according to an embodiment. The jacket 100 is designed to fit ergonomically and/or comfortably in a single hand of a user. In some embodiments, to facilitate an ergonomic and/or comfortable grip, the jacket 100 can include rounded contours and/or surfaces such that a user's hand is not exposed to sharp edges and/or corners. Further, the jacket 100 can be formed of a soft resilient material, for example, a polycarbonate material. In addition to providing the function of an ergonomic and/or comfortable grip, the jacket 100 can be configured to be aesthetically pleasing to the eye, in some embodiments.

Still referring to FIG. 1A, the jacket 100 includes a front cover 102 and a back cover (not visible in FIG. 1A) which form part of a protective case 104. The jacket 100 includes a receiving area 106 (indicated with dashed lines) configured to receive a handheld device, such as an iPod touch®. The front cover 102 includes a transparent screen 108 which is configured to align with a display on the handheld device. The transparent screen 108 can also be configured to allow a user to interact with a touchscreen or other input mechanism on the handheld device. The front cover 102, the back cover, and/or the case 104 can include one or more pass-through buttons, such as pass-through buttons 110 and 112, configured to align with input buttons on the device and allow a user to access the input buttons on the device through the jacket 100. In the illustrated embodiment, the buttons 110 are configured to align with volume control buttons on the handheld device and the button 112 is configured to align with a menu button on the handheld device. The jacket 100 can also include a speaker 114.

FIG. 1B shows a plan view of the front side of the jacket 100, including the front cover 102, the case 104, and the transparent screen 108. Inside the jacket 100, a connector assembly 116 is provided which is configured to connect to an accessory port on the handheld device. In some embodiments, the connector assembly 116 can include a 30 pin connector suitable for use with an iPod touch® and/or iPhone®. FIG. 1C shows a plan view of the back side of the jacket 100, including the back cover 118 and the protective case 104. The back side of the jacket 100 includes a transparent window 120, which can be aligned with a scan engine or scanner disposed inside the jacket 100. The scan engine can be a modular barcode scan engine such as a miniaturized, high performance 650 nm laser-based, single-line decoded scan engine from Symbol Technologies (model no. SE-923). The scan engine can be modular and self-contained, and can include a microcontroller configured to decode a barcode into a format compatible with and readable by the handheld device (or an application on the handheld device). In some embodiments, the scan engine is not configured to decode a barcode, and the terminal includes additional decoding or conversion circuitry configured to convert barcode data into an acceptable format for processing at slave microcontroller.

FIGS. 1D and 1E show left and right side views, respectively, of the jacket 100. As shown in FIG. 1E, the jacket 100 includes a scan button 122. The scan button 122 can be configured to activate the scan engine disposed inside the jacket 100. In some embodiments, the scan button 122 can be sized and shaped so that a user may hold the jacket 100 in one hand and manipulate the scan button with a thumb. In this way, the scan button 122 can be comfortably depressed or contacted by a user while viewing the screen 108 of the jacket 100. Although FIG. 1E illustrates the scan button 122 on the right side of the jacket 100, those having at least ordinary skill in the art will appreciate that the scan button 122 can be disposed on the left side of the jacket 100 so as to accommodate left handed users.

FIGS. 1F and 1G show top and bottom end views, respectively, of the jacket 100. As shown in FIG. 1F, the jacket 100 includes a pass-through button 124 which can be configured to align with an input button on the device and allow a user to access the input button on the device through the jacket 100. For example, the button 124 can be configured to align with a power button on the handheld device. As shown in FIG. 1G, the case 104 can include one or more openings, such as opening 126, configured to align with a connector on the connector assembly 116.

FIG. 1H shows a cross-section of the jacket 100 taken along line A-A of FIG. 1B, and illustrates certain portions of the jacket 100 in further detail. For example, FIG. 1H shows an intermediate member 128 which can be disposed between the front cover 102 and the back cover 118. Together with the front cover 102 (and the transparent screen 108), the intermediate member 128 can define the receiving area 106 for the handheld device. Together with the back cover 118, the intermediate member 128 defines a receiving area 130 for a battery 132, as well as a receiving area 134 for a scan engine 136. The battery 132 can include a lithium polymer battery configured to supply power to the scan engine 136. As mentioned above, in some embodiments the battery 132 can supply power to a handheld device as well. In this way, the battery 132 can power the components of the jacket 100 and/or the handheld device for an extended period of time, for example, 12 hours or more.

In some applications, the jacket (or a component thereof) can include firmware that communicates with the battery 132 and controls basic operations of the jacket 100. The battery 132 can be an extended battery, for example allowing the scanning jacket 100 to be used by a caregiver for a full 12 hour shift. In some embodiments, when a handheld device is placed within the receiving area 106 and the connector assembly 116 is connected to a charging connector (or other accessory port) on the handheld device, the scan engine 136 can communicate with the handheld device or with an application on the handheld device, such as an inventory or patient-safety application or other process control application on the handheld device.

The scan engine 136 can include a scan window 138, which may be disposed so as to face in a generally normal direction with respect to the general plane of the jacket 100 (for example, the general plane of transparent screen 108 through which the device display may be viewed). By such a configuration, a user may view the device display while scanning an object, by holding the jacket 100 over the object. In some embodiments, as illustrated in FIG. 1H, the scan window 138 can be configured to face at a slight angle from the normal direction (for example, an angle of about 5°, 6°, 7°, 8°, 9°, 9.5°, 10°, 10.5°, 11°, 12°, 13°, 14°, or 15° from the normal direction, or an angle greater than, less than, or between any of these two listed angles; or an angle of about 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 79.5°, 80°, 80.5°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, or 90° from a plane of the jacket 100, or an angle greater than, less than, or between any of these two listed angles). By such a configuration, a user may be able to see the object being scanned (such as, for example, an object being held in the user's other hand) just beyond the top of the device while the user is also viewing the device display. In this position, a user can also manipulate the scan button 122 with ease using a thumb. In other embodiments, the scan window 138 can be disposed so as to face a direction generally parallel to the plane of the jacket 100 (for example, straight ahead from the top end of the device), or at an angle to the top end of the device.

In some embodiments, as illustrated in FIG. 1H, the scan window 138 can be recessed within the jacket, while in other embodiments, the scan window can protrude from a surface of the jacket. In some embodiments, the scan engine 136 (and/or the scan window 138) can be movable (for example, rotatable) so as to allow a user to select or alter the angle and/or orientation of the scan window 138. FIG. 1I shows a cross-section of the jacket 100 taken along line B-B of FIG. 1B, and further illustrates the receiving area 106, the connector assembly 116, and the configuration of the front cover 102, the back cover 118, and the intermediate member 128.

FIG. 1J shows an exploded view of the jacket 100 and its various components, including the front cover 102, the back cover 118, the intermediate member 128, the scan engine 136, and the transparent window 120. As can be seen in FIG. 1J, the jacket 100 can include a microphone 148, which may form part of the connector assembly 116. The microphone 148 and the speaker 114 can both be liquid-proof and/or liquid resistant, and can be configured to allow use of a non-cellular device as a VoIP handset in a healthcare setting.

As can also be seen in FIG. 1J, the intermediate member 128 and the back cover 118 can be fastened together using a plurality of fasteners, such as screws 140, so as to enclose the scan engine 136 and the battery 132 within the jacket 100. The front cover 102 can also be fastened together using a plurality of fasteners, such as screws 142, to enclose the receiving area 106 and the connector assembly 116. One or more gaskets 144 can be provided around the edges of the seams between the front cover 102, the intermediate member 128, and the back cover 118 and configured to provide a seal or boundary for the receiving area 106. In this way, the receiving area 106 can be sealed from liquids (water, blood, bodily fluids, medications, cleaning agents, etc.) and/or solid particles (medical powders, dust, dirt, debris, etc.) that the jacket 100 may be exposed to in use.

In some embodiments, the seal for the receiving area 106 can be configured to meet an ingress protection rating or international protection rating required or preferred for a particular use. For example, the jacket 100 can be configured to provide an “IP54” protection rating for the receiving area 106. As used herein, an IP54 protection rating refers to an enclosure that protects against the ingress of dust and other small particles in a quantity that would interfere with the satisfactory operation of the handheld device and that also protects the handheld device from liquid that splashes against the jacket 100 from any direction. Of course, the jacket 100 can be configured to provide more, or less, protection against the intrusion of solid particles and liquids into the receiving area 106 to protect the internal components (for example, the handheld device).

In some embodiments, the jacket 100 can include an actuator 146 disposed between the intermediate member 128 and the back cover 118, in alignment with the scan button 122 on the case 104, which is configured to activate the scan engine 136. Once the handheld device is in place in the receiving area 106 and connected to the connector assembly 116, with the front cover 102 and back cover 118 fastened together and the gasket 144 in place, the case 104 can be pulled around the covers 102, 118 to provide drop resistance as well as a comfortable grip. In some embodiments, the jacket 100 can have a shape that is comfortable to grip and that is also pleasing to the eye. The exterior of the jacket 100 (including, for example, portions of the front cover 102, the back cover 118, the case 104, and the areas joining these components) can be configured to resist liquid splashes and cleaning materials, allowing the jacket 100 to be regularly cleaned as per usual healthcare procedures for infection control. In other embodiments, the front and back covers 102, 118 can be covered or coated with a drop-resistant (for example, compressible) and liquid-proof or liquid resistant material, without the addition of a flexible case, and can be provided with an interengaging structure configured to create a seal to prevent the ingress of water and cleaning fluids. In this way, the front and back covers 102, 118 can provide another seal to protect internal components housed within the jacket 100.

FIG. 2A shows a perspective view of a jacket 200 according to another embodiment. The jacket 200 includes a front cover 202 and a back cover 203. The jacket 200 includes a receiving area 206 configured to receive a handheld device, such as an iPod touch®.

FIG. 3A is a drawing showing the front of a jacket 300 according to another embodiment. FIG. 3B is a drawing showing the left side of the jacket 300. FIG. 3C is a drawing showing the right side of the jacket 300. FIG. 3D is a drawing showing the top end of the jacket 300. FIG. 3E is a drawing showing the bottom end of the jacket 300. FIG. 3F is a drawing showing the back side of the jacket 300, including screw holes 301, 303. FIG. 3G is a drawing showing the jacket 300 in an open position, with a connector assembly 305 exposed, ready to receive a handheld device. FIG. 4 is a drawing showing plugs 302, 304 that can be used to seal screw holes or openings 301, 303, respectively, in the jacket 300.

FIGS. 5A and 5B are drawings illustrating steps in the installation of a handheld electronic device 310 in the jacket 300. For example, with the jacket 300 in an open position (FIG. 5A), the handheld device 301 can be placed into the jacket 300 at a slight upward-facing angle. The connector assembly 305 is braced at the bottom (as indicated in FIG. 5B) and the device 310 is slid down fully to make a solid connection with the connector assembly 305. The front cover is then placed over the handheld device 310, in alignment with the back cover. After fasteners are installed in the corner screw holes 301 and the side screw holes 303, the plugs 302, 304 can be inserted into the corner screw holes 301 and the side screw holes 303, respectively, to seal the holes 301, 303.

As with the embodiments of jackets described above, the jacket 300 can include sealing or engaging structure to seal internal components, including the handheld device 301 and other electronic components, within the jacket 300. The jacket 300 can further include one or more batteries, an optical scanner, and/or a scanner engine. In this way, the jacket 300 and handheld device 301 can form a handheld terminal or computing device that may be used comfortably by a healthcare professional over the course of a work shift to perform one or more tasks. For example, a handheld terminal including the jacket 300 and handheld device 301 can be used to scan codes in a hospital environment without requiring power charges and with minimal risk of damage to the terminal from exposure to solid particles and/or liquids. Further, the jacket 300 can include one or more materials that can be repeatedly cleaned or disinfected using liquid agents without degrading over time.

FIG. 6A shows a perspective view of a jacket 600 according to another embodiment. As with the jackets described above, the jacket 600 can be used to form a handheld terminal or computing device along with a handheld device (not shown). For example, the jacket 600 can be configured to at least partially house and/or encase a handheld device, for example, an iPod touch®, such that the handheld device can be utilized to perform one or more tasks, such as tasks performed in a healthcare environment.

In some embodiments, the jacket 600 is designed to fit ergonomically and/or comfortably in a single hand of a user. As shown, to facilitate an ergonomic and/or comfortable grip, the jacket 600 can include rounded outer contours, edges, and/or surfaces such that a user's hand is not exposed to features. Further, the jacket 600 can be formed of a resilient material, for example, a polycarbonate material. In addition to providing the function of an ergonomic and/or comfortable grip, the jacket 600 can be configured to be aesthetically pleasing to the eye, in some embodiments.

Still referring to FIG. 6A, the jacket 600 can include an upper or front cover 602 and a lower or back cover 618. The front and back covers 602, 618 can form the outer surfaces of the jacket 600 that may be contacted by a user. Further, the jacket 600 includes a receiving area 606 configured to receive a handheld device, such as an iPod touch®.

A receiving area 606 can be disposed between the front and back covers 602, 618 and can be accessible through an opening 611 formed in the front cover 602. In some embodiments, the opening 611 can be sized and shaped so as to align with at least a portion of a screen, display surface, and/or input surface of a handheld device. In this way, a screen of a handheld device received within the receiving area 606 may be directly contacted via the opening 611. As a result, the sensitivity of pressure-based, capacitance-based, and/or optical-based touch input systems can be preserved via direct user contact through the opening 611 when a handheld device is disposed within the receiving area 606 between the front and back covers 602, 618.

As shown, the front cover 602 can include an outer portion 603 which meets an inner portion 607 at a leading edge 605. The outer and inner portions 603, 607 can be sloped such that the leading edge 605 is offset or disposed above the plane of the opening 611. In this way, the exposed screen of a handheld device disposed within the receiving area 606 can be offset or set back from the leading edge 605. Accordingly, the leading edge 605 may protect the screen from damage when the front cover 602 of the jacket 600 comes into contact with another object, for example, when accidentally dropped, by forming a leading point of contact with the other object. Further, the back cover 618 can include one or more resilient protrusions 691 extending outwardly from the center of the jacket 600. Such protrusions 691 can be sized and/or shaped to at least partially absorb impactful forces that the jacket 600 may be exposed to. For example, the protrusions 691 can be sized and/or shaped to absorb impact forces when one or more of the protrusions contact a ground surface during a fall. Additionally, the protrusions 691 can increase frictional forces between the jacket 600 and another object, for example, a clip board, desk, or counter, to inhibit unintended movement of the jacket 600 due to incidental forces.

The front cover 602 and the back cover 618 can include one or more pass-through buttons, such as pass-through buttons 610 and 612, configured to align with input buttons on the device and allow a user to access the input buttons on the device through the jacket 600. In the illustrated embodiment, the buttons 610 are configured to align with volume control buttons on the handheld device and the button 612 is configured to align with a menu button on the handheld device. The jacket 600 can also include a speaker 614 which can be connected with an audio out terminal of a handheld device, for example. In some embodiments, the front cover 602 can include a transparent window 609 to allow for a forward facing camera of handheld device to be optically exposed through the transparent window when the handheld device is disposed within the receiving area 606 of the jacket 600.

FIG. 6B shows a plan view of the front side of the jacket 600, including the front cover 602, the opening 611, and the receiving area 606. As shown, a battery 632 can be disposed within the jacket 600. In some embodiments, the battery 632 can provide a supporting surface to support a received handheld device above other components of the jacket 600 within the receiving area 606.

FIG. 6C shows a plan view of the back side of the jacket 600, including the back cover 618. In some embodiments, the back cover 618 can include a contact portion 619. The contact portion 619 can be sized and shaped to contact the inner portion of a user's hand that holds the back cover 618 of the jacket 600. In some embodiments, the contact portion 619 includes a scan button 622 disposed on a side of the jacket 600. In this way, in use, the inside of a user's hand can be disposed in contact with the contact portion 619 and the user's thumb may comfortably contact the scan button 622. In some embodiments, the contact portion 619 comprises a different material than other portions of the back cover 618. For example, the contact portion 619 can comprise a softer or less rigid structure that is comfortable to hold for extended periods of time. Further, the contact portion 619 can include an at least partially absorbent material to absorb oils and/or sweat from a user's hand.

Still referring to FIG. 6C, the back cover 618 of the jacket 600 can include a transparent scanning window 620, which can be aligned with a scan engine or scanner disposed within the jacket 600. The scan engine can be a modular barcode scan engine such as a miniaturized, high performance barcode scanning imager from Intermec (for example, model EA15). The scan engine can be modular and self-contained, and can include a microcontroller configured to decode a barcode into a format compatible with and readable by the handheld device (or an application on the handheld device). In some embodiments, the scan engine is not configured to decode a barcode, and the terminal further comprises additional decoding or conversion circuitry configured to convert barcode data into an acceptable format for processing at the slave microcontroller.

In some embodiments, the back cover 618 of the jacket 600 can optionally include another transparent window 693. The transparent window 693 can be aligned with a camera of a handheld device received within the jacket 600. Thus, the jacket 600 can form a handheld terminal including a handheld device which allows for scanning objects through the scanning window 620 and/or capturing images through the transparent window 693 via the handheld device. In some embodiments, the jacket 600 can include one or more lenses aligned with the transparent window 693 to alter the optical properties through the window 693. The back cover 618 also may include an opening 626, which will be described below with reference to FIG. 6G.

FIGS. 6D and 6E show left and right side views, respectively, of the jacket 600. As shown in FIG. 6E, the scan button 622 can be disposed on the right side of the jacket 600. The scan button 622 can be configured to activate the scan engine disposed inside the jacket 600. As discussed above, in some embodiments, the scan button 622 can be sized and shaped so that a user may hold the jacket 600 in one hand and manipulate the scan button with a thumb. In this way, the scan button 622 can be comfortably depressed or contacted by a user while viewing the screen of a handheld device through the opening 611 of the jacket 600. Although FIG. 6E illustrates the scan button 622 on the right side of the jacket 600, those having at least ordinary skill in the art will appreciate that the scan button 622 can be disposed on the left side of the jacket 600 so as to accommodate left handed user's, in some embodiments.

FIGS. 6F and 6G show top and bottom end views, respectively, of the jacket 600. As shown in FIG. 6F, the jacket 600 includes a pass-through button 624 which can be configured to align with an input button on the device and allow a user to access the input button on the device through the jacket 600. For example, the button 624 can be configured to align with a power button and/or hard reset on the handheld device. As shown in FIG. 6G, the jacket 600 can include one or more openings, such as opening 626, configured to align with a connector of a connector assembly disposed within the jacket 600.

FIG. 6H shows a cross-section of the jacket 600 taken along line A-A of FIG. 6B, and illustrates certain portions of the jacket 600 in further detail. For example, FIG. 6H shows a shield 628 which can be disposed underneath the battery 632 to shield underlying electrical components, for example, a scanner board and/or main circuit board. The battery 632 can include a lithium polymer battery configured to supply power to a scan engine 636. As mentioned above, in some embodiments the battery 632 can supply power to a handheld device as well. In this way, the battery 632 can power the components of the jacket 600 and/or the handheld device for an extended period of time, for example, 12 hours or more.

Still referring to FIG. 6H, the front cover 602 and battery 632 can form the receiving area 606 for the handheld device. Together with the back cover 618, the shield 628 defines a receiving area 630 for other components including a scanner board and/or main circuit board. In some applications, the jacket 600 (or a component thereof) can include firmware stored on memory of a main circuit board that communicates with the battery 632 and controls basic operations of the jacket 600.

In some embodiments, the scan engine 636 can include a scan window 638, which may be disposed so as to face in a generally normal direction with respect to the general plane of the jacket 600 (for example, the general plane of the opening 611 defined by the front cover 602). As shown, the scan window 638 can be at least partially aligned with the transparent scanning window 620 such that an optical path may be created between an object to be scanned and the scan engine 636 through the transparent scanning window 620 and the scan window 638. By such a configuration, a user may view the screen of the device while scanning an object, by holding the jacket 600 over the object and orienting the transparent scanning window 620 relative to the object to be scanned. In some embodiments, the scan window 638 may include one or more lenses, to alter the optical properties through the scan window 638.

In some embodiments, the scan window 638 can be configured to face at a slight angle from the normal direction (for example, an angle of about 5°, 6°, 7°, 8°, 9°, 9°, 10°, 10.5°, 11°, 12°, 13°, 14°, or 15° from the normal direction, or an angle greater than, less than, or between any of these two listed angles; or an angle of about 70°, 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 79.5°, 80°, 80.5°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, or 90° from a plane of the jacket 600, or an angle greater than, less than, or between any of these two listed angles). By such a configuration, a user may be able to see the object being scanned (such as, for example, an object being held in the user's other hand) just beyond the top of the device while the user is also viewing the device display. In this position, a user can also manipulate the scan button 622 with ease using a thumb. Thus, the user does not have to torque or twist the wrist to move between a position where an object is viewable but not scannable to another position where the object is scannable but not viewable.

In other embodiments, the scan window 638 can be disposed so as to face a direction generally parallel to the plane of the jacket 600 (for example, straight ahead from the top end of the device), or at an angle to the top end of the device. In some embodiments, as illustrated in FIG. 6H, the scan window 638 can be recessed within the jacket 600, while in other embodiments, the scan window can protrude from a surface of the jacket. In some embodiments, the scan engine 636 (and/or the scan window 638) can be movable (for example, rotatable) so as to allow a user to select or alter the angle and/or orientation of the scan window 638. FIG. 6H also includes a connector assembly 616, which will be described below with regard to FIG. 6I.

FIG. 6I shows a cross-section of the jacket 600 taken along line B-B of FIG. 6B, and further illustrates the receiving area 606, and a connector assembly 616. Inside the jacket 600, the connector assembly 616 is provided which is configured to connect to an accessory port on the handheld device. In some embodiments, the connector assembly 616 can include a 30 pin connector 615 suitable for use with an iPod touch® and/or iPhone®. The connector assembly 616 may be accessible through the opening 626 shown in FIG. 6G such that a handheld device disposed within the receiving area 606 may be connected to via the opening 626, the connector assembly 616 and the connector 615. In some embodiments, the connector assembly 616 can include a female usb port configured to convert a usb connection to a 30 pin connector through the connector assembly 616. In this way, a user may connect to the handheld device with a connection structure that is different than a pin configuration of the connection port of the handheld device. In some embodiments, when a handheld device is placed within the receiving area 606 and the connector assembly 616 is connected to a charging connector (or other accessory port) on the handheld device, the scan engine 636 can communicate with the handheld device or with an application on the handheld device, such as an inventory or patient-safety application or other process control application on the handheld device. In this way, firmware or applications of the jacket 600 may communicate with data and/or applications stored on the handheld device.

FIG. 6J shows an exploded view of the jacket 600 and its various components, including the front cover 602, the back cover 618, the battery 632, the shield 628, the scan engine 636, and the scanning window 620. As can be seen in FIG. 6J, the jacket 600 can a scanning engine bracket 645 and an optional speaker 644 disposed on the scanning engine bracket 645. The jacket 600 can also include one or more microphones such that the jacket 600 can be configured to allow use of a non-cellular handheld device as a VoIP handset in a healthcare setting.

As mentioned above, in some embodiments, the jacket 600 can include a scanner board 677 and a main circuit board 671. The main circuit board 671 can include a battery connector 673, a scanning engine connector 675, a scanner board connection 676, and a scan button connection 674. The main circuit board 671 may also be connected with an input port 617 and/or connector 615 of the connector assembly 616 via a cable 613 extending between the connector assembly 616 and the main circuit board. In some embodiments, the scanner board 677 can be connected to the scanning engine 636 via a flexible cable 679 routed therebetween. The jacket 600 can also include a vibrating element 682 disposed in the bottom cover 618 and electrically connected to the main circuit board 671. In this way, the main circuit board 671 can centralize the inputs and outputs of various electronic structures which may be housed within the jacket 600. In some embodiments, the jacket 600 can also include a bracket structure 651 configured to position internal components of the jacket 600 (for example, the battery 632 or shield 628) relative to the front cover 602 and back cover 618.

Still referring to FIG. 6J, in some embodiments the front cover 602 can include one or more compressible gaskets disposed on an underside of the front cover around the opening 611. In this way, the front cover 602 and the one or more gaskets can circumferentially engage or contact at least a portion of an outer surface handheld device (for example, an upper surface or screen) disposed within the jacket 600. As a result, the contact or engagement between the front cover 602 and the handheld device can be configured to provide a seal or boundary for the portion of the receiving area 606 disposed below the outer surface of the handheld device that is exposed through the opening 611. Thus, the receiving area 606 can be sealed or otherwise protected from liquids (water, blood, bodily fluids, medications, cleaning agents, etc.) and/or solid particles (medical powders, dust, dirt, debris, etc.) that the jacket 600 may be exposed to during use.

As discussed above, even though the portion of the receiving area 606 disposed below the outer surface of the handheld device may be sealed by the front cover 602 and outer surface of the handheld device, the outer surface of the handheld device may be directly contacted through the opening 611. In other words, the jacket 600 does not require a screen to be disposed over the handheld device to seal internal electrical components of a handheld terminal formed by the jacket 600 and the handheld device. In some instances, forming a seal between the jacket 600 and handheld device while allowing an input surface of the handheld device to be directly contactable can improve input sensitivity of the handheld device as compared with embodiments that utilize a separate screen over the handheld device. In some embodiments, the one or more compressible gaskets may be sized and/or shaped to absorb impactful forces on the jacket 600 to limit the transfer of these forces to the handheld device.

In some embodiments, the seal for the portion of the receiving area 606 disposed below the outer surface of the handheld device can be configured to meet an ingress protection rating or international protection rating required or preferred for a particular use. For example, the jacket 600 can be configured to provide an “IP54” protection rating for the internal electrical components (including internal components of the handheld device). Of course, the jacket 600 can be configured to provide more, or less, protection against the intrusion of solid particles and liquids. In some embodiments, the front and back covers 602, 618 can be covered or coated with a drop-resistant (for example, compressible) and liquid-proof or liquid resistant material, and can be provided with an interengaging structure configured to create a seal to prevent the ingress of water and cleaning fluids. In this way, the front and back covers 602, 618 can provide another seal to protect internal components housed within the jacket 600.
